分析德国媒体对巴西灾害报道的峰值，揭示国际关注的触发因素。
The Newsworthiness of Brazilian Distress: A Peak Analysis on Time Series of International Media Attention to Disasters in Brazil
- 通过时间序列分割识别新闻事件高峰
- 发现报道峰值与国内外灾害数据库存在时间对齐
- 为理解国际媒体关注机制提供实证数据
媒体报道影响灾害应对，但国际媒体关注本地事件的驱动因素仍不清晰。巴西是典型案例：其部分自然与技术灾害偶发登上国际头条，但系统性分析仍缺失。本文基于2000至2024年德国报纸中关于巴西火灾与滑坡的2000条新闻，采用时间序列分割方法检测新闻事件峰值，检验其与国家及全球灾害数据库记录的时间对齐程度，填补了国别化、可验证新闻数据集的空白。
原文摘要 · Abstract (English)
Media coverage influences disaster response, yet the drivers of international media attention to local events remain unevenly understood. Brazil offers a compelling case: some of its natural and technological disasters occasionally hit the international headlines. However, systematic analyses of what makes these events be discussed abroad are still missing. Addressing this gap requires representative, validated and country-specific news datasets. This paper presents a peak analysis of 2k news about Brazilian fires and landslides in German newspapers from 2000 to 2024. Using time series segmentation to detect news event peaks, we examine the extent to which they can be temporally aligned with observations in national and global disaster databases.
